.application tiled January :la Serial No. 674,045.

To all 'zlliom it mcg; con vi:

lie it known that l naivrtnvv el. Wotan, a citizen of the United States, residing in llinneapolis, in the countvoi Hennepin and State ci' ll'linnesota, have invented a new and useful. improvement in Faucets, o.- which the following is a specitication.

v T his invention to iniproven'ients i.v faucets,

The object of the invention is to provide a structure lin which the faucet shall be provided, in addition to the customary cock for regulating the iiow of water, with an. auxiliary or secondary autoniatimiil?,7 seit' closing shutoff valve to prevent the'escape and splashing of water whenever the main. valve struc-ture is removed for repairs.

My invention furthermore consists in the improvements in the parts and devices and in the combinations of the parts and devices herein shown, described or claimed.

ln the drawing forming a part of this specification, Figure 1 is a vertical section of a faucet showing my improvements applied thereto. Fil. -2 is a horizontal tion, taken on the line Q-2 of 1, looking in the direction oi the arrows. Fig. 8 is a horizontal section, taken on the line 3-3 of Fig. 1, and lookingy in the drleetion of the arrows and Fig. his au elevation in the core forming a part oi theseli closing main cock.

In the drawing, 10 denotes the main mem loer of the faucet or casing, rthe saine being provided with a spout 11 integrallyv formed therewith and having also a shank 12 exteriorlv threaded in the ordinary manner and adapted to receive the coupling nut 13 for securing the ends of the supply pipe 14 thereto, and having;r also a lock nut 15. rlhe casing 10 is provided with interior threads 16 adapted to receive the core 17, the latter containing" the various parts of the main cock. threaded thereinr a bushing 18, the same being provided with a valve seat 1S), upon which is adapted to be seated the main valve Q0. The bushing" 18 furthermore retains in place an elastic packing,r ,ring 21, the latter forming also preferably7 a part ot the valve seat for the valve 20. In the upper portion of the core 17 is provided a stutiing box formed hy means ot a packing 22 and hushing 23, the latter being threaded. to the interior of the core 17 and forming also a. cap

The core 17 at its lower end hasl l i I l l l for the spring 2i. which surrounds the stem of the, valve 20. Screwed to the reduced upper en i 26 ci the stein is a second spring cap il?. 'the core 17 provided with an upper annular lange QS which is adapted to retain in place an eli stic. packing rin 9,9, said .flange 28 being preferably milled so 'that the same maybe easily removed. l'inother packing ring' 50 is secured between the Q8 and' the nut 33.. the latter being threaded to the casing 10 and serving to retain all the parts ot the main valve in Secured to the interior of the nut si the upper end thereo is a hollow sleeve 'fitrhe 'same being provided with cam faces with which coperatie cam i'accs on ing member B5 rounded upper reduced eno Q5, the Vmember 35 being .rotatable b v means of the handle 36. An additional packing 37 is secured in place between the sleeve 32 and :out 3S threaded to the nut 31. The shank 12 of the cock is provided with an interior shoulder 39, and ahove the shoulder 39 is also provided with an interior thread 4t() in which is screwed a hollow bushing il, the latter being provided with a valve seat ft2 with which coperatcs the secondary' or auxiliary valve 43. T he valve 43 is provided with a feathered stern 4A and is oit such length that when engaged by the main valve 20, thc secondary valve lil will be held in an inoperative po sition, thus allowing they water to pass thi-muah thev sleeve 41 and to he controlled by the main valve 20. The internal shoulder "89 prevents the valve 43 from dropping down thc shank.

i tl e lower end oi? the operat f ich engages the l 26 or the stern The luishing 41 is pro vided with an upper external rim 45, and retains in place an elastic packing 46, and between the riin 4.5 and the lower end of the core 17 is also an additional packing ring 47. When the main valve is removed, it will loc ap,\iareut"'that the water pressure in the lpipe will automatically force the valve li-.l against its seat- 42 and retain it in such position, and thus prevent any. Waste or discharge ot water while the main valve and coperating parts are being` repaired,

I claim ln combination, and provided with a a casingr having a spout shank, a valve seat located within said shank, said shank being provided with an internal shoulder, a valve located within the shank between said valve meme@ seat and shoulder, said va'lve having a etem named valve, the first named vave being he'reon aA second valve sent located within adapted to be closed automatically by the 10 the casmg, n remevabe valve coperatng Water pressure when the second named valve therewith and opening against theu pres is removed.

sure, said last named valve normally being FRANKLYN J. WOLFF. adapted to engage said stem and thereby holding the rst named 'valve in its open po mien. and means for operating the second /Vitnesses:
